The search for a new Earth begins in latest 'Interstellar' trailer

The curtain is pulled back an inch on director Christopher Nolan's new scifi epic.

If last year's "Interstellar" teaser left you scratching your head, don't expect the latest full length trailer to offer many answers. Director Christopher Nolan's scifi epic has been shrouded in secrecy ever since production began, but there are some dots we can connect.

Remember that rumor last summer about climate change being a driving force behind mankind's search for a new world? It's not yet clear if that's still the case, but there's something going on that's destroying Earth's agriculture production. Corn, in particular, hasn't had this much of a starring role since "Signs" or even "Field of Dreams." Either way, Matthew McConaughey's character in "Interstellar" is forced to find a new world - because as Michael Caine's describes with his usual gravitas, we're otherwise doomed.

"We must confront the reality that nothing in our solar system can help us," says Caine in the trailer. "We're not meant to save the world. We're meant to leave it. And this is the mission you will train for."

In what's sure to bring a smile to Neil deGrasse Tyson's face (and also light up his Twitter account), "Interstellar" will also feature a heavy dose of space travel based on actual science. In a Reddit chat on the new trailer, one commenter mentioned how Nolan and his special effects team actually consulted his group for the specifics on what wormholes would actually look like.

"The simulations we showed to the team featured a simulated star field and a rotating black hole," he writes. "The black hole does appear dark, as no light is emitted from it. The bending of light seen around a black hole would be similar to that around a wormhole, which is why our simulations were useful. However, the main visual difference would be how the wormhole itself looks. Black holes can be thought of as one-way, not even light can escape from inside the event horizon. However wormholes are two-way objects. Light would be able to escape, although what you would see would be very distorted. This is why there is a large sphere of distorted light at 1:56 of the trailer."

Got that? Now check out the trailer below. "Interstellar" will be released November 7th.
